Vertical Tabs for Firefox 27 and beyond

This Firefox add-on arranges tabs in a vertical rather than horizontal fashion. It is heavily inspired by and borrows ideas from the excellent Tree Style Tab add-on.

Goals:

• Ability to arrange tabs in groups (instead of arbitrary trees) plus some group-related features (collapse group, tab previews, etc.)

• Very few other features and hopefully little or no preference settings. Instead a good JavaScript API might be provided for other extensions (e.g. JetPack SDK based) to provide additional features.

• Native look and feel.

• Readable and maintainable code, taking latest Mozilla practices into account. No eval() hacks.
